摘要
目的:探讨腹部超声子宫动脉血流参数对孕早期先兆流产及胎儿生长受限的预测价值。方法:收集本院2017年5月-2020年12月收治的96例孕妇临床资料,根据产前检查分为胎儿生长受限组(n=14),先兆流产组(n=16),正常妊娠的对照组(n=66)。均接受腹部超声检查,分析子宫动脉血流参数[收缩期峰值/舒张末期流速(S/E)、阻力指数(RI)、搏动指数(PI)],并采用受试者工作特征曲线(ROC)分析各参数预测孕早期先兆流产及胎儿生长受限价值。结果:胎儿生长受限组和先兆流产组左右侧血流参数S/D、RI以及PI水平无差异但均高于对照组(均P<0.05);ROC曲线分析,S/D、RI、PI预测孕早期先兆流产的灵敏度(80.0%、86.7%、80.0%)和特异度(83.3%、90.9%、92.4%),诊断胎儿生长受限的灵感度(86.7%、83.3%、73.3%),特异度(86.3%、87.9%、89.4%)。结论:腹部超声子宫动脉血流参数对孕早期先兆流产及胎儿生长受限有较好的预测价值。
Objective: To investigate the value of uterine artery hemodynamics parameters by transabdominal ultrasound of women for predicting their threatened abortion during the first trimester of pregnancy and fetal growth restriction(FGR). Methods: The clinic data of 96 pregnant women from May 2017 to December 2020 were enrolled and were divided into two groups according to the examination results, which included 14 women with FGR in group A, 16 women with threatened abortion group in group B, and 66 normal pregnant women in group C. All the women in the three groups received transabdominal ultrasound examination, and their uterine artery hemodynamics parameters, including systolic/diastolic ratio(S/D), resistance index(RI), and pulsatility index(PI) were analyzed. Then receiver operating characteristic(ROC) curve was used to analyze the predictive value of these uterine artery hemodynamics parameters of the women for their threatened abortion during the first trimester of pregnancy and their FGR. Results: There were no significant differences in the left and right uterine artery hemodynamics parameters, such as the values of S/D, RI, and PI of the women between group A and group B, and which of the women in group A and group B were significantly higher than those of the women in group C(all P<0.05). ROC curve analysis showed that the sensitivity of the S/D value, RI value, and PI value of the women for predicting their threatened abortion during the first trimester of pregnancy were 80.0%, 86.7%, and 80.0%, respectively. The specificity of the S/D value, RI value, and PI value of the women for predicting their threatened abortion during the first trimester of pregnancy were 83.3%, 90.9%, and 92.4%, respectively. The sensitivity of the S/D value, RI value, and PI value of the women for diagnosing their FGR were 86.7%, 83.3%, and 73.3%, respectively. The specificity of the S/D value, RI value, and PI value of the women for diagnosing their FGR were 86.3%, 87.9%, and 89.4%, respectively. Conclusion: The uterine artery hemodynamics parameters by transabdominal ultrasound of the pregnant women has better value for predicting their threatened abortion during the first trimester of pregnancy and their FGR.
